The present application discloses a secondary battery system including a mixed cathode material, a secondary battery management apparatus, and a secondary battery management method. The mixed cathode material includes at least a first cathode material and a second cathode material. The first and second cathode materials have different operating voltage ranges. The secondary battery system may further include a voltage relaxation mechanism for generating a voltage relaxation caused by actuation ion transfer between the first cathode material and the second cathode material when the secondary battery is in an idle state or a noload state, ). |
